[Discussion] Technical - Fuel Consumption

[raidknight]

yup.... true... EO change do make a noticeable difference in FC as well.. but for my case the biggest improvement was seen after carb washed and tuned (also depends on where and who wash and tune your bike)...

 

just for ur information my VerS now on SG road riding normally (rev about 6x1000rpm) can travel about 390km for a full tank... if go tour in Malaysia (rev high high) can travel about 330 or 340km on a full tank...

 

once again bro...

[tatboy]

my oil meter also not accur... sometime petrol still alot but is shown R liao... my full tank like onil can go 250 like that onil.. about 1L = 16km.. like siao siao lei.. or i calcu wrongly.. anyone know.. at which point of RPM change gear is better? what i heard is every gear change at 5000rpm nt more than that.. izzit true? ____ tatboy...VerS..

[Guest Eason]

mine like 20km per litre only leh

[calvinlim_83]

new bike i have tis problem too. left 2 bar travel only 160km. travel max 80km/h

[Hodaha_19]

like that, u shd keep ur bike cos not all spec 3 can attain this kinda FC.

yeah man.. mine 320-330 hit reserve.

[PaLmEr]

mine is ard 11-14km/L...

[richsg300]

mine hit 330 to 350 reserve riding style is 80 to 100km/hr.

[Hodaha_19]

Think got open VTEC or not to mi my FC is bout the same. maybe ur riding style bah. Needforspeed.

 

Btw ur bike is 1st hand ah? what i can think of is ur default fuel/air ratio maybe too rich liao. For what i know new bike push out from factory are on the rich settings but sometimes they might adjust it too rich then causing high FC. Do u notice any black smoke from ur exhaust when u high rev ur bike? Another way to verify is to take out ur spark plugs to see the colour, if very black then comfirm the factory adjust ur fuel/air ratio too rich.

my spec 2 after dynojet get 21-23km/l. i ride highway 100-140km/hr means vtec most of the time., some more using full system...

[nastrix]

I think it depends on our riding pattern

 

mine will hit reserve arnd 320km - 330km if i dun open the vtec that often

[eement]

ooo

my oso 410km full tank

reserve ard 360

[h0NDvvRE]

Izit true that wen a engine is cool and the more oxygen in the environment, the bike will have a better performance as well better fuel consumption.?

wow this Qns is hard...hope someone will help you on that...

:dozed:

like tat i must install a oxygen tank to my bike liao lohz..mayb full tank can reach 500km b4 reserve? haha

[ghost04]

max 320km b4 blinker. vtec on highway 120-140km/hr.

[Hodaha_19]

mine is 24km / litre

[FUbike]

recently changed to mobil and my mileage improved bit by bit...

used to be 260

now 300 and still havent blink and can still ride..

but blink means must immediately pump izit? or means using reserved? scared need to push bike...

[Hodaha_19]

For carb bike like S4 will enjoy abit of performance gain in cool weather, rainy days or at night when the air is cooler, why?

 

Physics 101, cool air has slightly more oxygen content percentage compare to warm air thus greater potential energy. When cooler air is mixed with fuel spray and feed into the combustion chamber and ignited, it will expand more than warm air thus releasing greater amount of energy per cm2 of air.

 

Thats why air compressed from a turbocharger must be cooled sufficiently via an aftercooler b4 it is force feed into the combustion chamber if not it will rob horsepower or worst pre ignite b4 the plugs can fire causing severe engine damage.

 

Btw if u feed pure oxygen into the engine, a single spark from ur plugs will dis-integrate ur engine block together with u along...

[FUbike]

wa laoz... so chimz... u replying with guy?
